An Austrian engineering firm debuted a new type of hovercraft at the Paris Air Show this week, claiming it can take off and land vertically without using any rotor blades or fixed wings.

The D-Dalus vehicle uses four contra-rotating turbines for propulsion, each reaching 2,200 rpm. Each turbine blade has a variable angle of attack, which according to the designer allows the main thrust to be fired in any direction, around any axis. This allows the craft to launch vertically, hover, rotate in any direction and even thrust upwards, holding itself down.

IAT21 has been working on a prototype for three years and has recently completed initial testing using a 120 bhp KTM engine to drive the turbines, according to Gizmag. The company completed tests transitioning from vertical to forward flight in a laboratory near Salzburg, Austria.
